The following is a general game guide for getting specific endings, as there are 10 to find, as well as some of the minor puzzles.

You'll want to pick each option in the order it's listed for each ending.

14. The 14th note is found in dad's office in the top desk drawer (and is only discoverable after you find the other 12 notes and return to the living room). You cannot return to the office after you leave, so if you miss this note, you can't return for it.

The Block Puzzle

The block puzzle is more easily solved if you've found most, if not all notes, although it's not necessary technically, and repeat players who proceed through the tunnel and solve the puzzle without all notes will be treated to a cheeky message.

The block puzzle is accessible through the tunnel, which is able to be found in the shed. Please note that the tunnel can only be entered at the right time, which is the end of the game and does not require you to have found all the notes to enter. If you can't enter the tunnel, it's because it's not time for it yet.

The notes you collect spell out an acrostic cipher which says "come play with me". This is the solution for the block puzzle.
